I haven't done anything with the OVP.
I've also heard there is some adjustment that can be made to the EHA? I haven't done anything with that. Could have that anything to do with the idle?
BTW, after new plugs, wires, fuel filter and O2 sensor I'm getting noticeably better mileage.

You can adjust the EHA via a small screw in the rear. MARK THE ORIGINAL POSITION.
Without use of a fuel pressure gauge you have no way to correctly adjust it. Mark the original position and give it turns in 1/8th's.
FYI Though: I HIGHLY doubt that is the cause of the rough idle though. Look at vacuum leaks at the idle control valve.
What does your economy gauge show at idle? Where is it at? Does it fluctuate at all?
Does the engine smooth out in neutral? Condition of motor mounts?
Is your ABS light illuminated? (OVP failure symptom)
